Queens: Puzzle

Queens is a colorful logic puzzle inspired by the classic N-Queens chess problem — simple rules, deep strategy.

THE GOAL
Place one queen in each colored region of the board. Sounds easy? Every queen must also sit alone in its row, its column, and cannot touch any other queen — not even diagonally. All four rules at once. No shortcuts.
